Other engine problem on the 2017 Kia Forte
2 crashes 2 fires 1 injury 5 of the 106 reports for this failure mention a crash, a fire, an injury or a death. Those are the owner's words on the complaint form, not a verified finding, and one report can mention more than one.
When other engine problem gets reported
Owners of the 2017 Kia Forte report other engine problem at a median of 77,500 miles. A quarter of the reports come in before 32,500 miles and a quarter after 97,500 miles, from 44 reports that carried an odometer reading.
A part like this is normally expected to survive 95,000 miles. It is the 1st most-reported problem on this model year.
The mileage distribution
The reported range runs from 10,000 miles at the tenth percentile to 132,500 miles at the ninetieth, a spread of 122,848 miles across the middle 80% of reports.
A spread this wide points at use rather than design. Towing, climate, service history and city mileage all move a failure like this, so the median is a weak guide to any individual car.
32% of the dated reports were filed under 36,000 miles.
The whole distribution
| 10th | 25th | Median | 75th | 90th |
|---|---|---|---|---|
| 10,652 miles | 31,500 miles | 77,500 miles | 98,652 miles | 133,500 miles |
Read the 10th percentile as “one report in ten arrived this early”. Exact figures are shown in this table because it is the table of record; everywhere else on the site they are rounded to the precision the sample can carry.
What a percentile can and cannot tell you here
These five numbers describe the readings owners gave, in order. The median is the middle one: half the reports arrived below it. The 10th and 90th are the edges of the bulk of the distribution, and the distance between them is the part worth reading. A tight spread — say 70,000 to 95,000 miles — points at something that wears out on a schedule, and the schedule is knowable. A wide one, 20,000 to 190,000, points at a fault that hits some cars and never troubles others, which means the mileage on the listing in front of you tells you very little about your odds.
What these figures are not is a survival curve. Every reading here comes from a car whose owner filed a complaint, so the sample contains only failures: it cannot say what share of the fleet made it past 150,000 miles untouched, because those owners had nothing to report. Nor is the mileage the moment of failure — it is the odometer reading as recalled at the time of filing, which may be weeks later and is sometimes rounded to the nearest ten thousand by the person typing it.
Percentiles are shown at all only once 8 readings exist for the vehicle and mode. Below that the middle of a handful of numbers is noise wearing a decimal point, so the figures are withheld rather than dressed up.
What happens, and what it costs
Of these reports, 2 a crash, 2 a fire and 1 an injury are mentioned. Owners write their own complaints and the agency does not verify them, so read this as what the reports say happened rather than as a confirmed count.
Putting it right typically runs $300–$4,000 at an independent US shop. That range is an editorial estimate held in this site's failure-mode catalogue, not a figure from NHTSA, and it is a repair cost rather than a diagnosis cost.
The same failure on other years
The same failure is reported on 14 model years of this car. It shows up earliest on the 2022, at a median of 20,000 miles, and latest on the 2011 at 115,000 miles.
By volume the 2014 carries the most reports, with 129; the 2017 has 106. A mode that appears across most years of a model is usually a design choice rather than a bad batch.
If one year stands out to the left, that is the year to avoid; if the whole line sits at a similar mileage, this is wear rather than a defect in one production run.

What owners wrote
Verbatim from NHTSA complaint narratives, trimmed for length. The mileage is the one the owner gave.
The vehicle is the s model, new for 2017, I have driven the car approximately 2,000 miles since leasing it in september 2016. The car has poor acceleration, especially going up hills and merging into traffic (moving, city). It hesitates at traffic signals (from a dead stop). The vehicle tends to sway side to side from time to time (moving, city), the vehicle is under warranty and has been looked at by two different kia dealers. A technician has rode along with me; felt my concerns, but cannot duplicate it. I was told in march 2017 that the computer had been "tweaked", but no further information.
My car begins randomly shaking. I have had all maintenance done at the kia dealership as per my warranty specifies. The last 4 weeks, my car will randomly shake violently while idle, attempting to accelerate in the different drive modes. Yesterday, june 21st, 2018, my car started shaking violently as I was parked at the food city in chattanooga on ooltewah ringgold road.I was on facebook video messenger with my friend eating a mcchicken. I dropped my sandwich and immediately popped the hood. Upon opening, I see the engine shaking violently as before. My friend witnessed it as well. I immediately called kia motors customer service. They called roadside service to tow the car back to the dealership in cleveland, tn. Today, 6/22/2018, kia claimed they were unable to duplicate the issue and blamed bad gas. Even though the shaking happened upon returning home. My car has continually done this even with me using shell, bp, or 100%gasoline. Kia refuses to give me a fair price for trading to another car. The engine also ticks. I asked about this at the time of purchase on jan 13th, 2017 by the sales associate matt hake and was told it was…
Vehicle was in motion, smelled something "off", within seconds engine burst into flames. Entire vehicle gutted. Kia literally just installed a new engine, starter, battery, and intake 2 days prior due to engine locking up - with 22000 miles.

How far this goes
Complaints are voluntary, so 106 is a floor and not a count of affected cars. Mileages are typed in by owners and cluster on round numbers. And the mode itself is assigned by software reading the complaint text, which is reliable in bulk and fallible one report at a time.

How common is other engine problem on the 2017 Kia Forte?
106 reports have been filed with NHTSA, about 2.1 per 1,000 vehicles. Complaints are voluntary, so this is a floor rather than a count of affected cars.
What this is and is not. These are the mileages at which owners chose to complain to a federal agency, which is not the same as the mileage at which the part fails on every car. It skews toward failures that happened outside warranty, cost real money, or frightened someone. It is still the only public dataset that carries failure mileage at all, and the shape of a few hundred readings is informative even when a single one is not.
